• tar Cannot stat: No such file or directory

  - by VVP

  Hi all, I have got this error in during my mail server backup: 2010-09-16 06:24:20 ERROR backup of /var/mail/vhosts failed: tar: Removing leading `/' from member names tar: /var/mail/vhosts/host-name/0/user-name/.maildir/cur/1284588471.Vfd00I16e0223M187263.server.host-name\:2,: Cannot stat: No such file or directory tar: /var/mail/vhosts/host-name/0/user-name/.maildir/cur/1284587441.Vfd00I16e0220M85965.server.host-name\:2,: Cannot stat: No such file or directory tar: /var/mail/vhosts/host-name/0/user-name/.maildir/cur/1284588863.Vfd00I16e0225M370937.server.host-name\:2,: Cannot stat: No such file or directory tar: /var/mail/vhosts/host-name/0/user-name/.maildir/cur/1284602404.Vfd00I16e022aM416444.server.host-name\:2,: Cannot stat: No such file or directory tar: /var/mail/vhosts/host-name/0/user-name/.maildir/cur/1284594551.Vfd00I16e0228M678444.server.host-name\:2,: Cannot stat: No such file or directory tar: /var/mail/vhosts/host-name/0/user-name/.maildir/cur/1284588944.Vfd00I16e0226M622591.server.host-name\:2,: Cannot stat: No such file or directory tar: /var/mail/vhosts/host-name/0/user-name/.maildir/cur/1284587271.Vfd00I16e021fM96119.server.host-name\:2,: Cannot stat: No such file or directory tar: /var/mail/vhosts/host-name/0/user-name/.maildir/cur/1284599458.Vfd00I16e0229M181400.server.host-name\:2,: Cannot stat: No such file or directory tar: Error exit delayed from previous errors Is it happened because user deleted his messages? Is there any way how to prevent this? Well I am assuming it can be happened not only with e-mail backup. Can I rely on tar & gzip as a mail backup system?

• Disable CTRL+mouse wheel zooming in Chrome?

  - by Peter Nore

  I'm a normal-sighted person and I would like to view pages at 100% all the time. I use keyboard shortcuts that involve CTRL a lot, so about twenty times a day I accidentally hit CTRL at the same time that I'm scrolling, which results in the page being reflowed and repainted. This in is annoying because it can take up to 30 seconds to fix the issue, depending on how complex the site layout is. On sites with dynamic layout such as Google Docs the problem is more serious; accidentally hitting CTRL+mouse wheel corrupts the display and forces me to refresh the page entirely, sometimes causing me to loose information in the process. I would like to either decouple CTRL+mouse wheel from zoom, or disable zoom functionality altogether. This is possible on Firefox by using about:config; is there a similar way to edit detailed settings in Chrome? Would I have access to the detailed settings if I used Chromium instead of Chrome? I'll probably jump ship back to Firefox if I can't solve this problem. There is a superuser question that asks basically the same thing I'm asking, but for Firefox and Internet Explorer exclusively. Other people on the Chrome forum have had related issues, but none have the same problem. "I would really like it if I could deactivate the auto zoom in/out." had "something with laptops and Windows 7", not the feature built into Chrome. Other people have had PDF specific issues, which doesn't concern me. I've also tried searching for extensions that allow you to disable the scroll; I had hoped that "Zoom Lock" would have the ability to lock the zoom at 100% and prevent CTRL+scroll wheel from distorting the display, but it doesn't work for my use case. Google Chrome version 9.0.597.84 (Official Build 72991) Operating System: Ubuntu 10.10

• Nginx : Proper use of limit_req_zone and limit_req

  - by xperator

  I have 2 website running on VPS. Their purpose is sharing music files and publishing news. Both of them use wordpress. What I am trying is that I want to prevent little hackers from flooding the webserver and putting stress on the server to make it crash. The problem is that after using limit_req_zone and limit_req my website became very slow. Browsing Wordpress control panel takes a long long time. I tried changing values but it didn't improve much. I guess the problem is Wordpress because it's the only script I am using on both front and back end. Here is the last setting which seems to be more responsive than others : limit_req_zone $binary_remote_addr zone=flood:5m rate=10r/m; location ~ \.php$ { limit_req zone=flood burst=100 nodelay; } What are the optimal values that should be used in my case (wp) ? I want the website have it's normal behavior, On the other hand stopping lifeless people from flooding. Another question, Is it safe and enough to use limit_req only on php files ?

• SMTP message rate control on Ubuntu 8.04, preferably with postfix

  - by TimDaMan

  Maybe I am chasing a bug but I am trying to set up a smtp proxy of sorts. I have a postfix server which receives all the email for a collection of servers/clients. It them uses a smarthost (relayhost=...) to forward it's mail to our corporate MTA. I would like to limit the number of messages an individual server can relay to prevent swamping the corporate MTA. Postfix has a program called "anvil" that is capable of tracking stats about mail to be used for such things but it doesn't seem to be executed. I ran "inotifywait -m /usr/lib/postfix/anvil" while I started postfix and sent a number of messages through it from a remote server. inotifywait indicated anvil was never run. Anyone gotten postfix/anvil rate controls to work? main.cf smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no append_dot_mydomain = no readme_directory = no myhostname = site-server-q9 alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = localhost relayhost = Out outgoing mail relay mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 10.0.0.0/8 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = 10.X.X.X smtpd_client_message_rate_limit = 1 anvil_rate_time_unit = 1h master.cf extract anvil unix - - - - 1 anvil smtp inet n - - - - smtpd

• Why does Exchange 2003 silently reject emails with large attachments?

  - by Cypher

  Our environment: Exchange Server 2003 Standard, single instance, running on Windows Server 2003 Standard. configured to not send/receive mail with attachments larger than 10 MB. NDRs are not enabled. The issue: When an external sender sends an email with an attachment larger than 10MB, Exchange, as configured, does not receive the message. However, the sender of that message does not receive any notifications from his own mail server that the message could not be delivered due to attachment size. However, if an external user tries to send an email to a non-existent user, they do receive a message from their mail server indicating that the user does not exist. Why is that, and is there anything I can do about it? It would be nice if the sender received notification that the attachment file size exceeds our limits and their message was never received... Update The Exchange server has a SpamAssassin box in front of it... could that have something to do with it? Here is one of the last lines from SpamAssassin's logs when searching for my test e-mails: mail postfix/smtp[19133]: 2B80917758: to=, relay=10.0.0.8[10.0.0.8]:25, delay=4.3, delays=2.6/0/0/1.7, dsn=2.6.0, status=sent (250 2.6.0 Queued mail for delivery) My assumption is that Spam Assassin thinks the message is OK and is forwarding it off to Exchange. Update I've verified that Exchange is receiving the message and generating an NDR. However, delivery of NDRs are disabled to prevent Backscatter. Is there something that I can do to get Exchange to send a bounce message to the sending mail server (or verify that message is being sent) so the sending mail server can notify its sender of the bounce?

• Recommendations for handling Directory Harvesting spam on Exchange 2003

  - by Aaron Alton

  Our Exchange server is getting slammed with anywhere between 450,000 and 700,000 spam messages per day. We receive about 1700 legitimate messages in the same time frame. Roughly 75% of the spam is directory harvesting. We currently have GFI MailEssentials installed. To it's credit, it's doing a very good job, but the sheer volume of spam that we're receiving, and the number of connections that our exchange server is making is preventing legitimate email from being delivered in a timely manner. GFI is set up to check for directory harvesting at the SMTP level, which I presume intercepts the mail before it hits the Exchange services , or goes through SMSE. This "module" is ordered at the top of the list, so (hopefully) dealing with the harvesting is consuming a minimum amount of server resources and bandwidth. My question is, is there anything I can do to prevent our Exchange server's connection pool from being eaten up by these spam hosts? We had to limit the number of concurrent connections being made by Exchange, because it was consuming all of our bandwidth. Thanks, in advance.

• How do I install Windows XP from an external hard drive?

  - by Plasmer

  I'm trying to install Windows XP Media Center edition by copying the install disc image to an external hard drive and making it bootable. Has anyone had success getting this to work on systems that can't boot from dvds/floppies? I'm basically working from this guide: http://www.dl4all.com/other/21495-install-windows-xp-from-usb.html Update - 2/15/10 I used WinToFlash on my laptop to format my usb hard drive from my install dvd (Windows XP Media Center Version 2005 with Update Rollup 2 from Dell) and selected "boot from usb device" at the boot selection menu and the windows installer started up. However, an error message came up saying that: "A problem has been detected and windows has been shut down to prevent damage to your computer." Originally on my desktop machine, I had 1 150Gb SATA drive, and 2 150 Gb SATA drives striped together using RAID. From the hard drive diagnostics, it appears the windows install on one of the RAIDed disks lost a block and this has been preventing me from booting up. I replaced the standalone drive with a new 1Tb SATA drive and disconnected the other hard drives. Could the message be indicating a virus is on the unformatted drive? or the usb hard drive? Update 2 - 2/15/10 The external hard drive didn't find any viruses when scanned. I tried installing Vista Home Premium 64bit SP1 using WinToFlash and that installed successfully onto the new 1Tb drive. WinToFlash was really easy to use and helped a lot, thanks!

• 9000+ different subdomains 301 to main domain, .htacess apache

  - by Karim

  I bought a domain that had various subdomains such as Kim.domain.com/whatever john.domain.com/whatever1 Lizo.domain.com/whatever2 Simon.domain.com/whatever1 And this was in the thousands, and also had links to these pages I'd like to do a 301 redirect for all these urls into http://domain.com Any idea how this could be done? This is for a apache web server and needs to be done via .htaccess I have implemented the solution from reading the answer below. RewriteEngine On RewriteCond %{HTTP_HOST} !^www. domain.com$ RewriteCond %{HTTP_HOST} !^$ RewriteRule ^/(.*)$ http:/ / www. domain.com/$1 [L,R=301] However I have a slight problem, I would like to redirect all subdomains + subfolders to http://www. domain.com/ With the exception of http: //domain. com/subfolder/, in which case I would like to redirect to http: // www.domain. com/subfolder/ [i.e. exception for no subdomain] I'm guessing I need to add an exception, what can I do to implement this. Note: example URLs above have had spaces added to them to prevent spam blocks for blocking the post.

• All application passwords lost on Windows 7

  - by Rynardt

  A couple of days ago I changed my Windows 7 login password. My laptop is on my company's domain, so password changes are done over the internal network. Since changing the password I noticed that all my saved Chrome passwords are missing. Also Skype, Windows Live, Internet Explorer and Outlook lost their saved passwords. I guess there could be more applications with lost passwords, but I have not opened them yet. This makes me think that most applications saves their passwords to a general password vault on the Windows system and this vault got somehow corrupted when I changed my domain login password for windows. Do anyone have any idea of how to fix this and prevent it from happening again? EDIT : More Info I do development work at the office, so most of the time I bypass the firewall and connect directly to the internet gateway. Now and then I would connect to the company wifi network to do printing and access files on a NAS. So by default my laptop does not connect to the wifi hotspot. On this occasion to update the password, I had to connect to the wifi. So referring to the comment by OmnipotentEntity below, could this have happened when the system rebooted without a connection to the network as the laptop does not auto connect to the wifi hotspot?

• SSL timeout on some sites, across all browsers, on Mac OS X Snow Leopard

  - by dansays

  For the past several weeks, I've been receiving "Error 7 (net::ERR_TIMED_OUT): The operation timed out" when I attempt to connect to either Twitter or Paypal via SSL. I get this specific error in Google Chrome, but the same problem occurs in both Safari and Firefox. Other sites work fine, and other computers on my network can access these two sites. I have no firewall settings that would prevent me from accessing these sites over port 443. I notice that both Twitter and Paypal both have "Verisign Class 3 Extended Validation SSL CA" certificates. It is unclear whether this is related to the problem. In an effort to troubleshoot, I attempted to open the test sites referenced on Verisign's root certificate support page, which worked fine. Just to be sure, I downloaded and installed the root package file and installed all included Verisign certificates. No joy. I feel like I've hit a dead end. Any ideas? Update the first: I also cannot connect to FedEx.com, who also has a Verisign Class 3 Extended Validation cert. Update the second: Aaaaaaand it fixed itself. I did nothing. Or, I did something that worked, but in a delayed fashion. Frustrating, but a win is a win. I'll take it.

• Apache httpd processes and PHP out of memory

  - by Ofri

  I have a VPS running apache-php-mysql on centos and a single drupal website installed. The VPS has 256MB of RAM (could be the root cause of all my problems... maybe I just need more). Whenever I try to open my website from multiple browser tabs (about 8... not 800) all at once, apache crashes! I have this on the log: [Wed Oct 24 11:26:31 2012] [error] [client xxx] PHP Fatal error: Out of memory (allocated 28049408) (tried to allocate 201335 bytes) in xxx on line 2139, referer: xxx I have read many many posts here, but I think there is something fundamental that I'm missing - If I understand correctly some php script tried to allocate 200K after allocating 28MB, and fails to do so. First question is: should this cause the apache to crash??? Next, I tried to look at 'top' command while I do my little test. Indeed I see 7 httpd processes, each reserving about 30MB - which explains why my RAM runs out. How do I prevent apache from creating new processes until it's out of memory? I tried configuring /etc/httpd/conf/httpd.conf like this: <IfModule prefork.c> StartServers 1 MinSpareServers 1 MaxSpareServers 1 ServerLimit 1 MaxClients 1 MaxRequestsPerChild 100 </IfModule> But got the same exact result! What am I missing? Thanks a lot!

• How can I get Haproxy to not log local requests?

  - by coneybeare

  I am trying to clean out some of the log clutter from my machines and am starting by removing requests that are generated from the server themselves. I have cache warmers running around the clock and I don't want these polluting the logs. I was able to get apache to stop logging local requests by adding a dontlog for the local IP: SetEnvIf Remote_Addr "RE\.DA\.CT\.ED" dontlog CustomLog "|logger -p local3.info -t http" combined env=!dontlog and now I am looking for something similar to put in a configuration for the Haproxy log. How can I prevent 127.0.0.1 requests from writing to the Haproxy log? UPDATE: 2/15/11 I use the excellent loggly service to pull out logs in the cloud, but I am seeing tons of logs like this: 2011 Feb 15 06:09:42.000 ip-10-251-194-96 http: RE.DA.CT.ED - - [15/Feb/2011:06:09:42 -0500] "HEAD /search/Nevad/predictive/txt HTTP/1.0" 200 - "-" "Wget/1.10.2 (Red Hat modified)" 2011 Feb 15 06:09:42.000 127.0.0.1 haproxy[10390]: 127.0.0.1:58408 [15/Feb/2011:06:09:42] www i-5dd7a331.0 0/0/0/8/8 200 210 - - --NI 0/0/0 0/0 "HEAD /search/Nevad/predictive/txt HTTP/1.1" and I want them gone. This question focuses on how to remove that haproxy log line from writing to the server side log in the first place.

• Using fedora 17 commandline 'mail' program cannot send to hotmail

  - by Eric Leschinski

  I am trying to use the console in Fedora 17 to send an automated email to myself. I run this: echo "email content" | mail -s "blah" [email protected] It works fine, google treats it as a spam email, but when you mark it not spam everything is cool. For Hotmail there are policies to prevent the email from being sent. I do this: echo "email content" | mail -s "blah" [email protected] And the email returns as undeliverable, the email does not even appear in the spam folder and I get this as a response: ----- Transcript of session follows ----- ... while talking to mx3.hotmail.com.: >>> MAIL From:<[email protected]> SIZE=685 <<< 550 DY-001 (BAY0-MC3-F8) Unfortunately, messages from 184.90.101.28 weren't sent. Please contact your +Internet service provider. You can tell them that Hotmail does not relay dynamically-assigned IP ranges. +You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. 554 5.0.0 Service unavailable So apparently hotmail doesn't like spammers so much, they they are blocking anything with a dynamically assigned IP range. Google does not do this. What is the easiest way to just get around this and send an email to hotmail and end up in their spam folder to be unblocked later by the user?

• Install VirtualBox on Ubuntu 12.04.1 (on [Samsung] Chromebook)

  - by iphonedev7

  I have dual booted Ubuntu Linux 12.04.1 LTS on my Samsung Series 5 ChromeBook, and am trying to run/install Oracle VirtualBox (from the generic .run file downloaded from their website). However, every time I try to run it (as root from the command line), it gives me the following error occurs: Please install the build and header files for your current Linux kernel. The current kernel version is 3.4.0 Problems were found which would prevent VirtualBox from installing. I have tried the version from the Software Center, as well as the command line installation, both of which gave me errors based on my linux-headers/linux-kernel/linux-[kernel]-image. Here's an error I keep getting (on the command line): First Installation: checking all kernels...

• IE6 does not follow 302 redirect - displays 404 instead

  - by Dexter

  One of our clients has reported that they are experiencing 404 (file not found) errors when attempting to navigate a website that we support. The behaviour only appears to affect her - other users on the same machine can navigate the website fine, but the problem follows her from one PC to another. I've had a good look through the IIS server logs and have identified the requests in question. The normal request pattern is as follows: POST /page.aspx - 80 - ... 401 1 0 POST /page.aspx - 80 DOMAIN/user ... 302 0 0 GET /anotherPage.aspx Request=833f80a5-f34c-4b0e-addb-d73e1ee1663a 80 - ... 401 1 0 GET /anotherPage.aspx Request=833f80a5-f34c-4b0e-addb-d73e1ee1663a 80 DOMAIN/user ... 200 0 However, requests for the affected user do not include a request for the redirected page, nor an entry for the 404, i.e.: POST /page.aspx - 80 - ... 401 1 0 POST /page.aspx - 80 DOMAIN/user ... 302 0 0 ... other unrelated requests Can anyone suggest what might trigger this behaviour, and how I might investigate the cause or prevent it from occuring? I read here that the Allow META refresh option in IE6 might trigger this behaviour, but I have not been able to replicate the behaviour by modifying this setting only.

• GIT : I keep having to merge my new branch

  - by mnml

  Hi, I have created a new branch and I'm working on it with others dev but for reasons when I want to push my new commits I always have to git merge origin/mynewbranch Otherwise I'm getting some errors: ! [rejected] mynewbranch -> mynewbranch (non-fast-forward) error: failed to push some refs to '[email protected]/repo.git' To prevent you from losing history, non-fast-forward updates were rejected Merge the remote changes before pushing again. See the 'Note about fast-forwards' section of 'git push --help' for details. You asked me to pull without telling me which branch you want to merge with, and 'branch.mynewbranch.merge' in your configuration file does not tell me, either. Please specify which branch you want to use on the command line and try again (e.g. 'git pull <repository> <refspec>'). See git-pull(1) for details. If you often merge with the same branch, you may want to use something like the following in your configuration file: [branch "mynewbranch"] remote = <nickname> merge = <remote-ref> [remote "<nickname>"] url = <url> fetch = <refspec> See git-config(1) for details. Why is it not automatic? Thanks

• How can one use online backup with large amounts of static data?

  - by Billy ONeal

  I'd like to setup an offsite backup solution for about 500GB of data that's currently stored between my various machines. I don't care about data retention rates, as this is only a backup of, not primary storage, for my data. If the backup is stored on crappy non-redundant systems, that does not matter. The data set is almost entirely static, and mostly consists of things like installers for Visual Studio, and installer disk images for all of my games. I have found two services which meet most of this: Mozy Carbonite However, both services impose low bandwidth caps, on the order of 50kb/s, which prevent me from backing up a dataset of this size effectively (somewhere on the order of 6 weeks), despite the fact that I get multiple MB/s upload speeds everywhere else from this location. Carbonite has the additional problem that it tries to ignore pretty much every file in my backup set by default, because the files are mostly iso files and vmdk files, which aren't backed up by default. There are other services such as EC2 which don't have such bandwidth caps, but such services are typically stored in highly redundant servers, and therefore cost on the order of 10 cents/gb/month, which is insanely expensive for storage of this kind of data set. (At $50/month I could build my own NAS to hold the data which would pay for itself after ~2-3 months) (To be fair, they're offering quite a bit more service than I'm looking for at that price, such as offering public HTTP access to the data) Does anything exist meeting those requirements or am I basically hosed?

• Apache inflate application/ with mod_filter

  - by BGT

  I need to prevent pdf objects from being gzipped. Really, this only needs to take place if the request is from the Mozilla browser (but since I can't get something as seemingly simple as no-gzip for application/pdf, I figure it's wiser to start there). From looking at the apache documentation on mod_filter, I've got the following: <Location /> FilterDeclare gzipDeflate CONTENT_SET FilterDeclare gzipInflate CONTENT_SET FilterProvider gzipDeflate deflate req=User-Agent $Mozilla/ FilterProvider gzipInflate inflate resp=Content-Type $application/ FilterChain +gzipDeflate +gzipInflate </Location> From my testing, the gzipDeflate filter is doing its job and all the pages without the Content-Type starting with application are being gzipped. But, the gzipInflate doesn't seem to be working at all. I've inspected the response in Firebug and verified that the Content-Type being sent down is application/pdf. I'll go ahead and ask a potentially stupid question though: The response's Content-Type header in its entirety read "application/pdf; charset=Windows-1252". Does that make any sort of difference or is $application/ presumably enough to catch that? Any help is greatly appreciated. One other point, the URL that returns the pdf object does not have the .pdf extension. The pdf itself is stored in an Oracle database as a blob and appended to the page when appropriate (all the urls in the system use the same baseline). This was part of an original inquiry by a helpful member at stackoverflow who pointed me towards mod_filter and suggested I post the question here.

• SSH attack CentOS Amazon EC2

  - by user37143

  Hi, I run a few Rightscale CentOS AMI based instances on Amazon EC2. Two months back I found that our SSHD security is compromised( I had added host.allow and host.deny for ssh). So I created new instances and done an IP based ssh that allows only our IPs through AWS Firewall(ec2-authorize) and chnaged the ssh 22 default port to some other port but two days back I found I was not able to login to the server and when I tried on 22 port the ssh got connected and I found that sshd_conf was changed and when I tried to edit sshd_config I found root had no write permission on the file. So I tried a chmod and it said access denied for 'root' user. This is very strange. I checked secure log and history and found nothing informative. I have PHP, Ruby On Rails, Java, Wordpress apps running on these server. This time I did a chkrootkit scan and found nothing. I renamed the /etc/ssh folder and reinstalled openssh through yum. I had faced this on 3 instances on CentOS(5.2, 5.4) I have instances on Debian as well those working fine. Is this a CentOS/Rightscale issue. Guys, what security measures I should take to prevent this. Please support me this is very critical. Thanks

• Optimal video resolution and encoding for recording games for YouTube?

  - by Rookie

  I want to record video from games, therefore I cannot use very large video resolution, but I still want to make the large video view to look as sharp as the original encoded video before upload. I tried to use YouTube's recommended 854x640 resolution, but it wasn't possible with h264 and the encoding software I used (Handbrake) converted it to a width of the nearest multiple of 4, which I think is a limitation of the h264 format. The video I encoded was sharp and fine quality, but when I uploaded it to YouTube, it lost a lot of quality and the preferred large video view looks almost as bad as a 320p video. I tried to wait a few days but it never got sharper (in case it didn't process it completely yet). So, which resolution and encoding options I should use, if I want the large video player to have the sharpest possible video, retaining the original video quality as good as possible? I noticed that recording with 640x480, the video was sharper than with 1280x720, so I'm not sure what im doing wrong here; both were h264. Is it anyhow possible to prevent YouTube from re-encoding the videos? I just wonder how people can make so sharp videos, while mine are all blurry after upload, but before upload they looked fine. I also tried YouTube's suggested bitrates with h264, but it didn't work any better.

• SFTP, ChrootDirectory and multiple users

  - by mdo

  I need a setup where I can put the contents of several user folders to a DMZ server from where external clients can download it, protocol SFTP, Linux, OpenSSH. To ease administration we want to use one single user for the upload. What does work is to define ChrootDirectory /home/sftp/ in sshd_config, set the according ownership and modes and define a home dir in passwd so that the working directory of the user fits. This is my structure: /home/sftp/uploader/user1/file1.txt /user2/file2.txt The uploader user can write file1.txt and file2.txt to the corresponding folders and by having the user folders (user1, user2) set to the users' primary group + setting SETGUID on the folders the users are able to even delete the files (which is necessary). Only problem: because /home/sftp/ is the chroot base dir the users can change updir and see other users' folders, though not being able to change into because of access rights. Requirement: We want to prevent users to change to /home/sftp/uploader/ and see other users' folders. My requirements are to use SFTP, have one upload user and every user must have write access to his home dir. Obviously it's not an option to use something like ChrootDirectory %h because every path component of the chroot path needs to have limited access rights, so as far as I understand this does not work.

• Windows 8.1 in a VMWare Workstation 10 guest's mouse is missing, but only sometimes

  - by Rob Perkins

  I have VMWare Workstation 10 running on a Windows 7 machine, hosting a k guest OS. Before upgrading to WS 10 I was using version 9, and the Win8 guest OS ran without difficulty or error conditions. Since upgrading and installing the most current VMWare Tools inside the guest after upgrading to version 10, there are circumstances where the mouse pointer is not visible; the mouse position appears stuck at a screen location which is not the center of the virtualized display; and mouse click and scrolling events still get processed. Once this begins happening I have to reboot the host machine to get it to stop. (VMWare Tools 9.6.1 build-1378637 is what the WS 10 software installed) The problem seems to correlate with whether the mouse is captured during Win 8.1's bootup process, before control is passed to the login screen. If I explicitly click the mouse into the guest OS and move it slowly around while the system is booting, then I see the mouse after clicking to lift the first screen and expose the password prompt, and there is never a problem within the guest. If I don't do this during bootup, there is no mouse pointer, with the symptoms listed above. I have tried removing and reinstalling VMWare tools, and the other steps published for "mouse problems" from VMWare's chaotic troubleshooting database. The problem persists. Is there a setting in the virtual machine's configuration which could prevent this behavior?

• How to change .htaccess file to work right in localhost?

  - by Manolo Salsas

  I have this snippet code in my .htaccess file to prevent users from hotlinking the server's images: RewriteEngine On RewriteCond %{HTTP_REFERER} ^$ [OR] RewriteCond %{HTTP_REFERER} !^http://(www.)?itransformer.es/.*$ [NC] RewriteRule \.(gif|jpe?g|png|wbmp)$ http://itransformer.es [R,L] Of course, it is not working in my localhost, but don't know how to achieve it. My guess is that I should change the domain name with any wildcard. Any idea? Update I've finally found out the answer thanks to @Chris solution: RewriteCond %{HTTP_REFERER} ^$ [OR] RewriteCond %{HTTP_REFERER} ^https?://%{HTTP_HOST}/.*/usuarios/.*$ [NC] RewriteRule \.(gif|jpe?g|png|wbmp)$ http://%{HTTP_HOST} [R=301,L] The /usuarios/ directory is because I only want to deny direct access to files inside this directory. Update2 For some reason, it doesn't work again. Finally I think that I found out a better solution: RewriteCond %{REQUEST_FILENAME} .*/usuarios/.*$ [NC] RewriteRule \.(gif|jpe?g|png|wbmp)$ http://%{HTTP_HOST} [R=301,L] I say better solution because what I want to deny is direct access to a file (image). Update3 Well, after a while I discovered above wasn't exactly what I wanted, so the next is definitive: RewriteCond %{HTTP_REFERER} ^$ [OR] RewriteCond %{HTTP_REFERER} !^https?://itransformer.*$ [NC] RewriteRule /usuarios/.*\.(gif|jpe?g|png|wbmp)$ - [R=404,L] Just two doubts: If I change the above to: RewriteCond %{HTTP_REFERER} ^$ [OR] RewriteCond %{HTTP_REFERER} !^https?://%{HTTP_HOST}.*$ [NC] RewriteRule /usuarios/.*\.(gif|jpe?g|png|wbmp)$ - [R=404,L] it doesn't work. I don't understand why, because %{HTTP_HOST} is equal to itransformer in my localhost, and it should work. The second doubt is why is shown the default 404 page and not my custom page (that is shown in all other 404 responses).

• Windows7 corrupted profile - prevention exists?

  - by Radek

  I have dedicated Windows7 (not on domain) virtual machine for overnight automation testing. Some commands (mySQLdump, tscon.exe) must be run under administrator account. Last week administrator account's profile was corrupted. I fixed it by renaming it in the registry and logging in as administrator. And today it is corrupted again. I use administrator account only to run above commands via runas. Also the computer is restarted via cmd - shutdown command - quite often. Especially every night before automation testing starts. I checked the comp for viruses - did full scan using avast although I believed that the comp is clean. Any idea how to prevent the profile to get corrupted again? update So the first log entry in event log is today from 1.15am and one of my scripts ran runas command as administrator exactly at 1.15am. It was second time that runas war executed though after the testing started. The same happened second day in a row. Before the testing starts I need to copy one file that is locked. So I run handle.exe from runas to unlock it. That is what I think causing the profile to get corrupted. I am not able to reproduce it by myself. The message from event viewer is Windows cannot load the locally stored profile. Possible causes of this error include insufficient security rights or a corrupt local profile. DETAIL – The process cannot access the file because it is being used by another process.
